' and useful Improvements in Power Transmission, of which the cation.

following is a specifiinvention providesimeans for utilizing the powerof an automobile, enabling the automobileto be used as a stationary power plant. To this end the traction wheels of the automobile'are raised from the ground and brought into power-communicating relation toa shaft forming part of the novel equipment, so that the automobile-engine will supply'its power through the traction wheels to the power shaft of said equipment.

, Among the objects of my invention are to provide a device that is simple, inexpensive, adj ustable to meet the requirements imposed by differences in sizes and relative conformation of parts ofditferent automobiles, and arranged for facility of operation so that it may conveniently be worked by one man. In the drawings, wherein I have illustrated. an embodiment of my invention, I Figure 1 is a perspective view of the appliance in use.

Fig. 2 is a longitudinal section therethrough.

Fig. 3 is a'plan view. Fig. 4: is a detail of the saddle, etc. Fig. 5 is a section on line 55 of Fig. 2. Fig. Gis a section on line 6-(3 of Fig. 2. Generally the equipment embodying my invention provides means for lifting the 40 automobile A, and bringing its traction wheels as into working cooperation with the power shaft 10. The power'shaft 1( ca'rrying driven wheels 11 for peripheral engage- .ment with the traction wheels a, and carrying also a pulley wheel 12, (typifying any suitable means for power-delivery) is mounted for adjustment along a frame 13 of adjustable inclination thatpreferably receives ground bearing on the side bars 1& at its rear end, and that has itsfifront end supported, adjustably as to' height, on front This frame carriespreferably wheels 15. v between the forward and rearward groundbearings, saddles 16 forengagement with the rear axle housing a of an automobile, said saddles being movable as by levers 17, both to elevate the rear end of the automobile (to remove the traction wheels a from contact with the ground) and to bring said traction wheels into engaging Contact with the driven wheels 11 on the frame. For this purpose the saddles are preferably pivoted'and are positioned above their'pivotal axis.

In the specific construction shown, each side member 14 of the frame is composed of two angle irons 14 and 1 1, disposed to form jointly a split-T-arrangement with a slot 18 between the contiguous sides of the angle-irons. The two side members of the frame are connected by angle or channeled cross braces 19 and 20, so that the frame bodyis in effect a metallic rectangle with longitudinally slotted side members. Such construction is advantageous and inexpensive. The bearings 21 for the power shaft 10 are connected to the side members by bolts 22 taking through the slots 18, so that the shaft may be adjusted fore and aft on and of course the power delivery pulley l2 may-be applied at any point on the shaft that is desired.

The rear end of the frame may be permitted to rest directly on the ground so'that the sharp corners of its angle iron side members constitute holding points, but of course the extremities of the frame may be shod. for su port in other fashion if desired.

he front end of the frame is supported, preferably on the small Wheels 15, in such fashion that the frame as a-whole stands'at an angle to. the ground, and preferably so that the front extremity of-the frame may be raised or loweredat will. 15 are mounted on a cross shaft 24: connecting the extremities 'oftwo leg-members 25, (preferably curved. and rib-strengthened) each of which has a broad web 25,

The driven frictionlThus wheels' with an arcuate edge, passing into the slot 18 of the appropriate side member 14. the extremity of which is pivoted as at 26 to the front or leg portion of the bracket at or below the center from which the edge-arc is struck. A bolt 27 taking through the side member 1% of the frame into any one of a series of apertures 25 in the arcuate web portion of the leg, enables the angle between the leg and the f ame to be varied thereby to vary the elevation of the front end of the frame and consequently its inclination.

Each saddle-casting 16 is pivoted at 30 to the leg structure 25 above the frame pivot 26. so that manifestly b v rocking the saddle from a point in front of its vertical dead-center. toward dead center position, the concaved seat of the saddle will be both elevated and retracted. ln specific construction the saddle member 16 provides a bearing head 33 concaved to coi'iperate with an automobile axle bruising. a stem 34 divided into parallel limbs 35 that straddle the top portion of leg 2.) to receive the pivot 30, and a lever-attaclnnent-stub 3t that has an offset portion 3? between its ends. This o'tl'- set is overlain by the lever 17 that is bolted in place, as at 38. thereby afl'ording in the offset a rectangular guide-eve 39. For retaining the lever-operated saddle in any position of adjustment the lever must be locked in relation to the frame. Preferably web 25' of each adjustable front leg 25 is provided with an arcuate extension arni 4O struck from pivot 30 as'a center. .This arm passes through the eve 39 and has a number of holes 41 to receive a locking pin 412 that passes through openings in the sides of the eye.

Inoperation the vehicle and the powerconverting equipment are brought into proximity, it being easy to wheel the equipment around on its front wheels. wheel-barrow fashion. upon occasion. The legs are preliminarily adjusted at 27 so that the saddles 16 stand at approximately the height of the rear axle housing. The bearing brackets 21 for the power shaft are adjusted longitudinally in slots 18 so that the peripheries of driven wheels 11 are removed from the pivotal points 30 for the saddles at a distanee a little less than the radius of the vedriven wheels 11.

plropon draws it rearwardly, bringing the wheel tires into frictional drivin contact with the The ie course, then secured by pins.42 in such working position to maintain the driving relationship.

While I have herein described in some detail a particular embodiment of my invention, involving some refinements that are advantageous and that I may specifically claim for their advantages, it will be apparcut to those skilled in the art that in its broad aspect my invention is not limited to the details illustrated for purposes of full disclosure and that many changes may be made in the construction without departure from the spirit of my invention and within the scope of the appended claims.
